  1. Values are means ±SE. Data analyzed by repeated measures two-way ANOVA with baseline adjustment and Tukey-Kramer post hoc tests
  2. CON control, MRT moderate load resistance training, HRT heavy resistance training
  3. Significant interaction denoted by *(p < 0.05) or **(p < 0.01). Main effect of time denoted by ‡(p < 0.05) or ‡‡(p < 0.01). Post hoc tests: B: significant difference from CON12 (p < 0.05)
